Answer:
The correct answer is -
Numerator = 6
Denominator = 73
Explanation:
In F static test or table there are two sets of degrees of freedom: one for the numerator and one for the denominator. The degrees of freedom are equal to the number of observations minus one. Thus, if the sample size were 7 then the degree of freedom would be 7 minus 1
Numerator df = 7 - 1 = 6
Thus, the numerato would be - 6.
Denominator is calculated by subtracting the observation or variables from the total number of sample size.
Denominator df = 80- 7 = 73
Answer:
Carrying capacity can be described as the maximum number of population of a species that a particular habitat can hold.
There are a number of events which effect the carrying capacity like:
Environmental changes like weather conditions might become favorable for a species in a habitat. It might be that a certain weather condition raises more food for a species. Hence, the carrying capacity would increase.
It might be conditions like drought make the availability of nutrients scarce for a population of species. In this case, the carrying capacity of the ecosystem would decrease.
It might happen that other species might come to live in the particular area. That species will deplete the availability of resources and cause the carrying capacity to decrease.
If adequate amount of rain fall occurs in an area, it might cause the carrying capacity of a species to increase as there will be more water. But if the water supply becomes scarce, the carrying capacity would decrease.
I think the answer is C but i am sorry if i am wrong i took this test but i am pretty sure it is C have a good day and good luck on the test
